3.A Ask a testable question to determine how an object’s material (structure; independent variable) influences the amount of light transmitted and reflected (function; dependent variable).
What to look / listen for
As students work in pairs to construct testable questions, listen and look for
accurate identification of the dependent variable (amount of light reflected and amount of light transmitted) and the independent variable (one-way mirror, glass, and regular mirror), and
an understanding of the cause-and-effect relationship between the dependent and independent variables.
What to do
Listen for the independent and dependent variables and the cause-and-effect relationship students identify as they construct their testable questions. Use that information to anticipate how you will guide day 2’s whole-class discussion and to consider the kinds of questions you might need to ask.
